UI is always a mix of usability and discoverability, I think. The color wheel is perfectly usable, but little changes might affect discoverability.
That said, I think far too many UIs (window managers, etc) confuse the two. I'm only a newbie at a system _once_. If it takes a little longer to learn, then it's totally worth some initial confusion.

I'd hope that if it takes longer to learn because of initial confusion, that it's worth it because it's better than something that took less time to learn or that didn't have initial confusion. I'm not so sure I'd want to bear the cost of initial confusion just for the "benefit" of it taking longer to learn.
Talking about the colors, when I draw text, then click on the wheel to change the color, it doesn't work. I need to change the font(?) then, it refreshes itself.
